JACOB K. BUTLER, OF YARMOUTH, CANADA.

IMPROVEMENT IN FASTENINGS FOR WINDOW-SASHES.

Specification forming part of Letters Patent No. 118,512, dated August29, 1871.

To all whom it may concern:

Be it known that I, JACOB K. BUTLER, of

Yarmouth, in the Province of Nova Scotia and to allow them to be turnedinward for washing,

repairing, or other purposes; and it consists in the combination ofcertain devices with Wooden strips which slide up and down in thecasing, the connection being such that the sash may be turned inward orremoved. The office of said device is to hold the sash to the strips, orto liberate them therefrom, as described hereinafter.

In the accompanying drawing, Figure 1 represents a sectional front viewof a window with the front casing off. Fig. 2 is a cross-section of Fig.1 taken on the line new. Fig. 3 is a detail, showing the holdin g-hookdetached from the casing. Fig. 4 is a detail, showing the hook attachedto the casing. Fig. 5 is an edge view of a window-sash, showing thedetachable strip in place on the sash.

Similar letters of reference indicate corresponding parts.

A is the lower, and B the upper sash. C is the casing. D represents thedetachable strips on each stile of the sash. These pieces are at tachedto the sash by tongue and groove, as seen in Fig. 2. E is the cord; F,the weights by which the sashes are balanced. In Fig. 5 the back side ofthe strip D is shown. The cord is confined in a groove in the strip, butattached to the bottom of the sash, as represented. G is a hook in eachof the strips D, confined in a mortise and attached by a pivot-screw, asseen in Figs. 3 and 4. H is a small spring, by which the hook is pressedinto the mortise so as to keep the hook within the mortise as the sashis raised and lowered in ordinary use. I is a slotted plate in thecasing for each of the hooks. J is a slide in the sash for each hook,placed opposite the hook, so that when shoved upward it will strike thehook at the point K and force it through the plate I, onto which plateit will hook, as seen in Fig. 4. Fig, 3 shows it in the other position.

When the sashes are raised and lowered, as in ordinary use, the strips Dwill be held or kept in place by the casin g. Their lower ends will reston the projections L of the sash, to which projections the cords areattached. Now, when the strips D are detached or hooked onto the casing,as seen in Fig. 4, the sash may be turned over or removed withoutdifficulty. To do this the lower sash is raised entirely up, the slidesJ are pushed upward, so that the hooks engage with the plates I. Thissecures the strips 1) to the casing, when the sash may be lowered,leaving the strips D hanging, and be turned over and inward, or removedentirely from the casing. The upper sash is detached in the same manner.

By this arrangement access is obtained to the ouside of the sashes forwashing, putting in glass, or other purposes, with very little trouble.

The advantages of this improvement are many, and must be apparent toall.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The, hook G, slide J, and plate I, in combination withthe piece or strip D, substantially for the purposes described.
